Configure Virtual Networks in Hyper-V Server 2008 R2

Applies To: Microsoft Hyper-V Server 2008 R2

You can configure one or more virtual networks for virtual machines to access network resources.

To configure virtual networks

  1. Go to any computer that you have previously set up for remote management of Hyper-V Server.

  2. Start the Hyper-V Manager MMC snap-in.

  3. From the Actions menu, click Connect to Server, select Another Computer, and then enter the name or IP address of the server that you want to connect to.

  4. In the Actions menu, click Virtual Network Manager.

  5. Under Create virtual network, select External, and then click Add.

  6. Type a name for the new virtual network (such as Corpnet), and then click OK.

When you create a virtual network remotely, Hyper-V Server creates the new virtual switch and binds it to the TCP/IP stack of the physical network. If the server running Hyper-V Server is configured with only one physical network adapter, this may result in a loss of network connection. When you create the external virtual switch, ensure that you select the Allow management operating system to share this network adapter check box in Step 5 in this procedure to avoid this situation. A drop of the network connection is normal during the creation of the virtual switch on the physical adapter.
